Expert writing Tips

Best practice

Use "know how to" when you want to emphasize practical skill or competence in performing a specific action. For instance, "She knows how to fix a car" suggests she has the practical ability, not just theoretical knowledge.

Common error

Avoid using "know how to be able to". The phrase "know how to" already implies ability, so adding "be able to" is redundant. Simply use "know how to" for a more concise and clear statement.
